Description

&Quot; A DEVICE FOR TRANSMITTING GEARS "

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gear shifting device, and more particularly, to a gear shifting device that shifts a gear by only shifting direction control without selecting direction control.

BACKGROUND ART [0002] Generally, a vehicle is provided with a transmission for changing the gear engagement so as to adapt to a backward movement or a running state, as a power transmission device for transmitting an output of an engine or a motor to a drive wheel.

In the case of a manual transmission, gear shifting is performed directly by operating a manual shift lever. However, a transmission using an electric actuator also has a structure using both a select motor for select operation and a shift motor for seat operation. There is a structure in which the select motor is omitted and the shift is performed only by the shift direction control as shown in Fig.

1, shift lugs 150 are provided corresponding to each shift rail 101, and cam-shaped control fingers 120 for actuating each shift lug 150 are connected to a single control And is fixedly coupled along the longitudinal direction of the shaft 110. [ When the driver operates the shift lever, the control shaft 110 rotates to rotate the control finger 120, and the shift lug 150 corresponding to the control finger 120 is pressed to move the shift rail 101, To the gears of the first and second gears.

The control angles of all the control fingers 120 are controlled only by rotating the single control shaft 110 so that the shift of the control shaft 110 in the select direction can be omitted.

However, gear shifts of a single control shaft structure require precise angle control because they must be arranged with different cam angles of the entire control fingers within the rotation angle of one control shaft. In addition, since the cam angle difference from the smallest control finger to the largest control finger is large, there is a problem that the rotation radius of the control shaft becomes large in order to shift the entire speed change stage, thereby causing a large shift time. For example, the control shaft must be rotated 360 degrees to shift all gear positions.

The present invention has been made in order to overcome the problems of the conventional gear transmission as described above, and it is an object of the present invention to provide a gear transmission which can reduce a shift time by operating a shift stage with a plurality of shift structures, The present invention has been made in view of the above problems.

In order to achieve the above object, a gear shift device according to the present invention is a gear shift device having shift lugs corresponding to respective shift rails and having a cam-shaped control finger for operating each shift lug, The control fingers are dispersedly coupled to a plurality of control shafts rotating independently of each other.

In the gear shift device according to the embodiment of the present invention, the control shaft may include a first control shaft in which a part of the control fingers is fixedly coupled and integrally rotated, and a control shaft coupled to the first control shaft And a second control shaft rotatable integrally with the first control shaft and hollowed to fit outside the first control shaft and rotating independently of the first control shaft.

In the gear shift device according to the embodiment of the present invention, the second control shaft may be provided coaxially with the first control shaft.

In the gear shift device according to the embodiment of the present invention, the control fingers may include a first control finger and a second control finger fixedly coupled to the second control shaft at different cam angles, It is also possible to include a third control finger and a fourth control finger which are fixedly coupled with different cam angles.

In the gear shifting device according to the embodiment of the present invention, each of the control fingers can operate the two shift lugs in opposite directions.

In the gear shift device according to the embodiment of the present invention, a guide groove is formed in an inner wall of the second control shaft along its longitudinal direction, and a guide groove of the second control shaft is formed on an outer peripheral surface of the first control shaft Guide protrusions can be formed so as to be fitted.

The guide groove and the guide protrusion may be formed in such a manner that the first control shaft and the second control shaft are rotated in the state where the cam angles of the first control finger and the third control finger are adjusted to be the same, May be formed to assemble.

In the gear shift device according to the embodiment of the present invention, when the first control shaft rotates relative to the second control shaft, the rotation groove, which the guide projection pivotally receives along the circumferential direction, May be formed on the shaft.

In the gear shift apparatus according to the embodiment of the present invention, the first control shaft and the second control shaft may be rotated by different shift actuators.

In the gear shift apparatus according to the embodiment of the present invention, the shift actuator may include a first actuator for rotating the first control shaft, and a second actuator for rotating the second control shaft.

In the gear transmission according to the embodiment of the present invention, the shift actuator may be two shift levers.

As described above, according to the gear shifting apparatus of the present invention, the shift time can be shortened as compared with the case where the control fingers are divided into the plurality of control shafts so that the shift fingers are dispersedly combined to form a single shift mechanism. The control performance can be improved.

FIG. 2 and FIG. 3 are combined perspective views of a gear transmission according to an embodiment of the present invention,
Fig. 4 is an exploded perspective view of the gear transmission shown in Fig. 3,
FIGS. 5 and 6 are side views showing the control shaft and the control finger shown in FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 to 6, a gear transmission according to an embodiment of the present invention includes a first control shaft 10, a hollow second control shaft 10 fitted to the outside of the first control shaft 10, A first control finger 31 and a second control finger 32 fixed to the first control shaft 10 and a third control finger fixedly coupled to the second control shaft 20 33 and a fourth control finger 34.

The first control shaft 10 is formed as a solid shaft and the second control shaft 20 is formed as a hollow shaft so that the second control shaft 20 is fitted to the outside of the first control shaft 10 . That is, the second control shaft 20 has a shaft through hole 21 through which the first control shaft 10 is inserted.

The first control shaft 10 and the second control shaft are provided coaxially and rotate independently of each other. That is, when the first control shaft 10 rotates, the second control shaft 20 does not rotate, and the first control shaft 10 rotates together even if the second control shaft 20 rotates no.

Control fingers are dispersedly coupled to the outer circumferential surfaces of the first control shaft 10 and the second control shaft 20. That is, some of the control fingers are fixedly coupled to the first control shaft 10, and the other control fingers other than the control finger coupled to the first control shaft are fixedly coupled to rotate integrally. In the present embodiment, four control lugs are provided to operate eight shift lugs 50 each for two. Each of the control fingers actuates the two shift lugs in opposite directions. The shift lugs 50 are provided so as to correspond one-to-one to shift rails (not shown).

Thus, the first control shaft 10 and the second control shaft 20 are independently rotated without being interlocked, so that the control fingers can be shared and operated. For example, the first control shaft 10 and the second control shaft 20 can be operated by sharing two of four control fingers. In this case, the first control shaft 10 and the second control shaft 20 The number of the control fingers divided by the control fingers is reduced by half, thereby reducing the turning radius of each control shaft, thereby shortening the shifting time.

The first control finger 31 and the second control finger 32 are fixedly coupled to the second control shaft 20 and the third control finger 33 and the fourth control finger 34 are fixedly coupled to the first control finger 20, And is fixedly coupled to the control shaft 10.

The first control finger 31 and the second control finger 32 have different cam angles on the first control shaft 10. The first control finger 31 and the second control finger 32 are rotated integrally with the second control shaft 20 so that the first control finger 31 and the second control finger 32 are rotated with different shift lugs . For example, when the first control finger 31 operates the first shift lug 51 by rotating the second control shaft 20 by a predetermined angle, the adjacent second shift lug 52 is not operated, When the second control shaft 20 further rotates, the first control finger 31 moves out of the first shift lug 51 and at this time the second control finger 32 actuates the second shift lug 52 do.

The third control finger 33 and the fourth control finger 34 also have different cam angles. Accordingly, when the third control finger 33 operates the third shift lug 53 by rotating the first control shaft 10 by a predetermined angle, the adjacent fourth shift lug 54 is not operated, When the first control shaft 10 further rotates, the third control finger 33 moves out of the third shift lug 53 and at this time the fourth control finger 34 actuates the fourth shift lug 54 do.

Since the second control shaft 20 operates only the first control finger 31 and the second control finger 32 of the four control fingers, the first control finger 31 and the second control finger 32 ) Are different from each other. Therefore, it is easier to design the cam angle than in the case where the four control fingers have to be implemented with different cam angles on one control shaft.

The third control finger 33 and the fourth control finger 34 of the four control fingers 33 are operated only in the first control shaft 10 and the fourth control finger 34 ) Are different from each other.

The first control finger 31 actuates the first shift lug 51 and the second shift lug 52 and the second control finger 32 actuates the third shift lug 53 and the fourth shift lug 54 The third control finger 33 actuates the fifth shift lug 55 and the sixth shift lug 56 and the fourth control finger 34 actuates the seventh shift lug 57 and the eighth shift lug 56, The shift lug 58 is operated. The first shift lug 51 to the seventh shift lug 57 respectively operate a 7-speed shift rail (not shown) in a 1-speed shift rail (not shown), and the 8th shift lug 58 Shift shift rails (not shown) are shifted.

A guide groove 22 is formed in the inner wall of the shaft through hole 21 of the second control shaft 20 along its longitudinal direction. A guide protrusion 11 is formed on the outer peripheral surface of the first control shaft so as to be fitted along the guide groove 22 of the second control shaft 20.

The guide groove 22 and the guide protrusion 11 serve to align an assembly angle when the second control shaft 20 is assembled with respect to the first control shaft 10. The first control shaft 31 and the third control finger 33 are aligned with the same cam angle so that the first control shaft and the second control shaft are assembled, (11) are formed.

The guide groove 22 is formed along the longitudinal direction of the second control shaft 20 so that even after the second control shaft 20 is assembled to the first control shaft 10, The first control shaft 10 and the second control shaft 20 are prevented from rotating relative to each other. The second control shaft 20 is formed with a rotation groove 23 so that the guide protrusion 11 is pivotally received along the circumferential direction of the second control shaft 20.

The rotation groove 23 allows the guide protrusion 11 to rotate together with the first control shaft 10 so that the first control shaft 10 and the second control shaft 20 It becomes relatively rotatable.

The first control shaft 10 and the second control shaft 20 are rotated by different shift actuators.

The first control shaft 10 is rotated by the first actuator 41 and the second control shaft 20 is rotated by the second actuator 42. [

The first actuator 41 and the second actuator 42 may be composed of an electric motor and a gear assembly. In this manner, when there are two actuators, the first actuator 41 is driven or the second actuator 42 is driven in accordance with an operation signal for shifting the respective gear positions. For example, when the driver performs the first-stage and second-speed shifting, the transmission signal drives the second actuator 42 to rotate the second control shaft 20. When the third-speed and fourth-speed transmission are performed, (41) to rotate the first control shaft (10).

Meanwhile, the first control shaft 10 and the second control shaft 20 can be operated by two manual shift selectors (not shown).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that the modification or the modification is possible by the person.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
